I was recently asked to create an iOS app for a client which controls all other installed apps' access to cellular data. For instance, the user would be able to turn off cellular data access to all apps but Safari.
I assumed that this wouldn't be possible because of sand-boxing but couldn't find any relevant info via Google or the developer's docs, so thought I'd ask the question here - is there a specific class or framework I should investigate?
No you can't , Apple does not allow such approaches . So there is no helping class or framework at all.
